1. Before starting, carefully check whether the electric sand pump is deformed or damaged during transportation, storage and installation, and the fasteners will loose or fall off;
2. Check the cable of submersible sand pump to avoind damage, breakage, etc. If there is damage, it needs to be replaced to avoid leakage;
3. Check that the power supply unit of submersible sand pump is safe and reliable, and the rated voltage must match the nameplate;
4. Check the cold insulation resistance of the stator winding of the motor with a megohmmeter to a value of not less than 50M;
5. It is strictly forbidden to use the cable of the pump as the installation and hoisting rope to avoid danger;
6. The direction of rotation of the submersible sand pump is counterclockwise as seen from the water inlet. If it is reversed, any two wires in the cable must be adjusted to the wiring position, and the pump can be rotated forward;
7. The submersible sand pump should be submerged into the water vertically. It is not allowed to be placed horizontally and cannot be trapped in the sludge. When the pump moves, the power must be cut off.
8. After the electric submersible sand pump is used for many times, it must be put into clean water for a few minutes to prevent deposits in the pump and ensure that the pump is clean;
